splyntra 1.3.0

Splyntra SDK - Agent observability & security, built on OpenTelemetry

Splyntra Python SDK

Unified observability and security for AI agents in Python. Built on OpenTelemetry, the Splyntra SDK captures every agent step, LLM call, and tool invocation as a structured trace — enriched with real-time risk scoring for leaked secrets, PII exposure, and prompt injection.

Installation

pip install splyntra

With framework auto-instrumentation:

pip install "splyntra[langgraph,openai]"

Available extras: langgraph, openai, openai-agents, crewai

Getting Started

Initialize once at application startup. The instrument parameter enables automatic tracing for supported frameworks — no per-call changes required.

from splyntra import Splyntra

Splyntra(
    api_key="splyntra_dev_key",
    project="my-app",
    endpoint="http://localhost:4318",
    framework="langgraph",
    instrument=("langgraph", "openai"),
)

# Run your LangGraph / OpenAI agent as usual — spans are captured automatically.

To instrument separately (e.g., after configuring the client elsewhere):

from splyntra import instrument

instrument()                 # auto-detect all installed frameworks
instrument("langgraph")      # or target a specific one

Manual Instrumentation

For custom agent, tool, and LLM functions, use decorators. Both sync and async functions are supported.

from splyntra import trace_agent, trace_tool, trace_llm

@trace_agent(name="support_agent", workflow="refund")
def run(query: str):
    customer = read_customer("42")
    return call_llm(query)

@trace_tool(name="crm.read")
def read_customer(id: str):
    ...

@trace_llm(model="gpt-4o", provider="openai")
def call_llm(prompt: str) -> dict:
    # Return a dict with a "usage" key for token/cost analytics
    ...

Configuration

Parameter	Default	Description
api_key	required	Splyntra API key (sent as Bearer token)
project	required	Project slug
endpoint	http://localhost:4318	Collector base URL
environment	development	Deployment environment label
service_name	value of project	OpenTelemetry service.name resource
framework	None	Framework label shown on the Agents page
redact_by_default	True	Strip secrets from spans before export
instrument	None	Tuple of frameworks to auto-instrument

Client-Side Redaction

High-confidence secrets (AWS keys, JWTs, bearer tokens, API keys) are stripped from span attributes before they leave your process. The collector applies a second pass on ingest as defence-in-depth.

Disable with redact_by_default=False (not recommended for production).

Supported Frameworks

Framework	Extra name	Span mapping
OpenAI SDK	openai	Chat completions → llm_call spans
LangGraph	langgraph	Graph run → agent span, nodes → step spans
OpenAI Agents	openai-agents	Runner.run → agent span
CrewAI	crewai	Crew kickoff → agent, tasks → step, tools → tool_call

Each instrumentor is a safe no-op when its target package is not installed.

For out-of-process platforms (Dify, n8n), see Integrations.

Evaluation

Run scored evaluations against the Splyntra evaluation service. The CLI exits non-zero on regression, making it suitable as a CI gate.

from splyntra import eval as ev

ev.push_dataset("support-qa", [{"input": "...", "expected_output": "..."}])
result = ev.run(dataset_id, results=[{"input": "...", "actual": "..."}], gate=True)

splyntra eval push --name support-qa --file dataset.jsonl
splyntra eval run  --dataset <id> --file results.jsonl --gate

Governance

Request delegation decisions and record consequential actions to the immutable ledger:

from splyntra import authorize, log_action

decision = authorize(
    "payments.refund",
    agent_id="support_agent",
    context={"amount": 80},
)

if decision["decision"] == "allow":
    # proceed with action
    ...
elif decision["decision"] == "needs_approval":
    # routed to human approval in the dashboard
    ...

log_action("refund", actor="support_agent", resource="order_42", metadata={"amount": 80})
